Vulnerabilidades

A flaw was found in rpcbind. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service (DoS) by sending a large number of unique requests. The rpcbind service records previously unseen RPC (Remote Procedure Call) statistics in unbounded in-memory lists, leading to persistent memory…

A stack-based buffer overflow was found in rpcbind's rpcinfo utility. In rpcbdump() short mode (used by `rpcinfo -s`), version numbers from a remote RPCBPROC_DUMP reply are written into a fixed-size stack buffer without bounds checking. A user or administrator who runs `rpcinfo -s` against a malicious or compromised…

A stack-based buffer overflow was found in rpcbind's rpcinfo utility. When querying a remote rpcbind service with `rpcinfo -l`, address information returned by the server is copied into a fixed-size buffer without sufficient bounds checking. A malicious or compromised rpcbind server could use this flaw to crash the…

rpcbind 0.2.0 allows local users to write to arbitrary files or gain privileges via a symlink attack on (1) /tmp/portmap.xdr and (2) /tmp/rpcbind.xdr.

rpcbind 0.2.0 does not properly validate (1) /tmp/portmap.xdr and (2) /tmp/rpcbind.xdr, which can be created by an attacker before the daemon is started.

rpcbind through 0.2.4, LIBTIRPC through 1.0.1 and 1.0.2-rc through 1.0.2-rc3, and NTIRPC through 1.4.3 do not consider the maximum RPC data size during memory allocation for XDR strings, which allows remote attackers to cause a denial of service (memory consumption with no subsequent free) via a crafted UDP packet to…

Use-after-free vulnerability in xprt_set_caller in rpcb_svc_com.c in rpcbind 0.2.1 and earlier allows remote attackers to cause a denial of service (daemon crash) via crafted packets, involving a PMAP_CALLIT code.
